The Third Expedition Window has closed in ARC Raiders, and the Fourth is already on the horizon. With the June 22, 2026 opening date, you have roughly six weeks from when the Project first became available to pull everything together. That sounds generous until you see the Stage 5 requirements. Start now.
When does the Fourth Expedition Window open?
The Fourth Expedition Window opens on June 22, 2026. A live countdown is visible in-game when you preview the Project, so you can track the exact time remaining without leaving the client.
The wipe end date has not been confirmed by Embark Studios at the time of writing. Based on how the Third Expedition played out, the wipe window could run anywhere from five days to two full weeks after the Window opens. Embark has acknowledged the controversy around damage-dealt being tied to Skill Point bonuses and is actively reworking the rewards structure, so the specifics of the Fourth wipe may shift before June.
Any progress you made toward the previous Expedition Project carries over. If you started Stage 2 last wipe and didn't finish, you pick up from there rather than starting over.

What are all five stages of the Fourth Expedition Project?
The Project has five stages, each with four requirements. The difficulty ramps sharply by Stage 4, and Stage 5 is a pure Coin-sink that will catch unprepared players off guard. Here is every requirement listed by stage:
The total Coin requirement for Stage 5 alone is 750,000 Coins worth of supplies sold. That is not a typo. Plan your looting and selling strategy around hitting that number well before June 22.
Stage 5 requires selling specific categories of supplies, not just any items. Pay attention to whether you are selling Combat Items, Survival Items, Provisions, or Materials, as each category has its own threshold.
How should you prioritize each stage?
Stages 1 and 2: Get these done first
Metal Parts, Plastic Parts, and ARC Alloy are the most common loot-run pickups in the game, so Stage 1 should clear quickly if you are running regular expeditions. The 15x Steel Spring requirement is the one to watch here since springs drop less frequently than bulk materials.
Stage 2 shifts toward electronics. Wires and Electrical Components show up consistently in industrial zones, but the 4x Cooling Coil requirement will slow you down. Coils are not rare, but they are specific enough that you should actively prioritize them rather than hoping they appear.
Stage 3: The Exodus Modules bottleneck
Stage 3 is where most players stall. The 1x Exodus Modules requirement is the hardest single item to obtain in the entire Project. Everything else in this stage, including 30x Battery and 10x Shredder Gyro, is manageable with consistent runs. Lock in the Exodus Modules first and treat the rest as background progress.
Stage 4: Rare ARC components
Frequency Modulation Box, Ion Sputter, and Leaper Pulse Unit are all ARC-derived components that require targeting specific enemy types or high-tier loot zones. The 5x Advanced Electrical Components requirement is more straightforward by comparison. Treat Stage 4 as the gear-check stage: if you are not running the right areas with the right loadout, the drop rates will feel brutal.
Stage 5: The Coin grind
Selling 750,000 Coins worth of supplies is the real endgame of this Project. Breaking it down by category:
- Combat Items: 200,000 Coins
- Provisions: 150,000 Coins
- Materials: 300,000 Coins
- Survival Items: 100,000 Coins
Materials carry the heaviest weight at 300,000 Coins, which makes sense given how much raw loot you accumulate through normal play. The key is not hoarding. Sell consistently across all four categories throughout your runs rather than saving everything for a single session.
Is the Fourth Expedition worth doing?
The short answer is yes, assuming Embark continues improving the reward structure. The Third Expedition had real issues with how damage-dealt metrics tied into Skill Point bonuses, and Embark confirmed they are iterating on the system. The rewards for completing the full Project are meaningful enough that skipping it entirely is leaving progression on the table.
The wipe tied to the Fourth Window is also not mandatory. If you had a strong Third Expedition run and do not want to reset, you can still complete the Project without wiping. The decision becomes more interesting if Embark sweetens the wipe incentives before June 22.
